Troubleshooting
Can I use a device with Bluetooth technology on airplanes?
With Bluetooth technology, your computer transmits a radio frequency of 2.4 GHz. Sensitive locations, such as hospitals and
airplanes, may have restrictions on use of Bluetooth devices, due to radio interference. Check with facility staff to see if use
of the Bluetooth functionality on the computer is permitted.
Why can't I connect to a Bluetooth device by specifying its IP address on a Personal Area
Network (PAN)?
The Bluetooth utility software uses Dynamic Host Configuration Protocol (DHCP) to assign IP addresses to active wireless
devices. If you specify a fixed IP address for the device to which you want to connect, the utility cannot assign a dynamic IP
address to the device and fails. Do not specify IP addresses when using a PAN.
Why can't I use the Bluetooth functionality when I log onto my computer as a user with a
standard user account?
The Bluetooth functionality may not be available to a user with a standard user account on your computer. Log onto the
computer as a user with administrator rights.
Why can't I connect to a Bluetooth device in Personal Area Network User mode?
If the device to which you want to connect supports Bluetooth communication in Personal Area Network User mode only, you
cannot establish a connection from your computer.
Why can't I use the Bluetooth utility software when I switch a user?
If you switch a user without logging off from your system, the Bluetooth utility software will not work successfully. Make sure
to log off before switching a user. To log off from your system, click Start, the arrow next to the Lock button, and Log Off.
